Which DP had the best life before her happily ever after?

Pocahontas
Belle
Ariel
Aurora

It probably had to suck being so isolated, even more than Anna was, but Aurora seemed happy.

I think Pocahontas was better off before her "happily ever after" ariel and jasmine were kind of miserable before so....

By "best life," do you mean how they felt about their life before, or if it was just in general good? If you're talking about how they felt about it, then probably Aurora, Belle, and Jasmine. Aurora seemed like she had a easy going life in the woods with her three fairys. Belle seemed really happy with just her books and helping her dad out with his inventions, and Pocahontas was just free. In general, Ariel, Jasmine, and Merida. Ariel was the daughter of the ruler of the sea's, and had the most beautiful voice in the sea's, therefor she got off pretty easy. Jasmine was the daughter of the Sultan, and basically could get whatever she wanted (except choice in marriage). And Merida was a princess in a huge Scottish castle (those are probably the most beautiful castles you could ever see and be in) with servants running around and making sure her needs were placed.
